CLAUDE M. BOLAND, OF NEW YORK, N.

GLOVE-SEWING MACHINE.

SPECIFICATION forming part of Letters Patent No. 400,432, dated April 2, 1889.

Application filed May 12, 1888. Serial No. 273,704. (No model.)

T 0 all whont it may concern:

Be it known that I, CLAUDE M. BOLAND, of

r the city, county, and State of New York, have invented certain new and useful Improve- -ments in Glove-Sewing Machines, of which the following is'a specification.

This invention relates to improvements on the glove-sewing machine of the class de larged detail plan View of the stitching and feeding mechanism, showing my improvements in position; and Fig. 4 is a detail sectional view, enlarged, on the plane of the line a c, Fig. 8.

In the accompanying drawings, the letter A represents the casing that contains the operative mechanism of the glove-sewingmachine.

B is the inner feed-disk, that is journaled on a support, a, 011 the casing A.

D is the outer feed-disk, that is carried by a rod or arm, I), that passes into the casing A,

and connects with a spring which presses the d1sk D against the disk B to hold the fabric to be sewed.

F is the needle-bar, that projects from the casing A and moves the needle (1 to and fro above the disks B D.

G is the looper-bar, that projects from the casing A and carries the looper H, as herelnafter shown.

The proper spool-carrier and tension devices are shown on the top of the casing A.

The construction of the above parts and the mechanism for operating them will be found in the patent above mentioned, and I therefore need not refer more particularly to said parts herein, but refer to said patent for required details. I I

Heretofore when the looper took a loop from tected on all sides.

the needle it was apt to lift the needle with the loop, and thereby bent and frequently broke said needle. To obviate this difficulty special but intricate devices for holding down the needle have been introduced; but I use a very simple means for holding down the needle and at the same time guiding the loop. For this purpose I attach a needle protector or plate, I, to the arm b above the disk D, and groove the inner end of said plate I obliquely, so as to form a lip, d, that extends over the needle, as in Fig. 3. If the needle is drawn upon by the looper engaging its loop, the lip 61 will prevent the needle being raised. By this means the needle is guided and pro- When the loop on the needle is drawn back, it will be guided in the oblique slot, and thus the stitch is made more regular.

The looper-bar G, that receives longitudinal, vertical, and oscillatory motion from the mechanism within the casing A, is provided onits free or outer end with a horizontal socket, e, as clearly shown in Fig. 4. This tubular end of the looper-bar G is or may be slit longitudinally, as shown in Fig. 4, to form spring-jaws, and is surrounded by a collar, f, that-carries a screw, g. This screw 9 acts to close the clamping-jaws of the looper-bar G tightly on a horizontal rod, h, that passes within the socket e, whereby said rod his held to and may have longitudinal adjustment on the looper-bar; but the rod h may be otherwise suitably held to the looper-bar, G-as, for example, by the means shown in my former patent, No. 202,695. The outer or free end of the rod It has an inclined or nearly-vertical socket, 1?, which may be slitted, as in Figs. 1

and 3, to form clamping-jaws. j is a screw that passes across these clamping-jaws and by which said clamping-jaws are adjusted. The shank of the looper Hpasses into the socket t', and is held therein by the screw j and clamping-jaws; but said shank could be held in the socket '5 directly by the screw pressing upon it, or by any other suitable means.

By the above construction the looper H may be adjusted vertically with relation to or toward and from the side of the needle J, so that needles of different thickness or loopers varying in length may be used and the length of the loop adjusted. By means of the rod h and socket e the looper H may be adjusted horizontally or lengthwise of the needle in .the ordinary manner.

The nearly L-shaped and merely horizontally-adjustable loopers heretofore used are objectionable because they cannot be vertically adjusted. They are frequently, when put in a machine, found either too long or too short.

L is the ordinary fabric-guide that projects from the casing A and extends along part of the periphery of the inner feed-disk, 13, above said disk on the fabric-receiving side thereof, the needle passing along the end of said guide, as shown in Figs. 1 and 3.

L is a guide similar to L, and projects from the casing and passes along part of the periphery of the inner feed-disk, B, and above said disk on the side opposite to the guide L- that is to say, on the side from which the fabric issues-as shown in Fig. 3. The free end of the guide L projects close to the end of the guide L, sufficient room being left between them for the passage of the needle J. With this construction the fabric E that is between the disks B D will be fed along by said disks, and the additional guide L will prevent the fabric turning over as it leaves the needle, thereby producing better Work than has been done where the guide L was not used and the fabric was permitted to turn over after leaving the needle. The two guides L I, also c0- operate with the needle-guard I to hold the fabric above the feed-disks properly compressed for the formation of a good stitch.

Having now described my invention, what I claim is 1. In a sewing-machine, the needle guard or protector I, having an oblique slot for the needle, combined with the looper and needle and with fabric-feeding mechanism, substantially as described.

2. The needle guard or protector I, having an oblique slot for the needle, and a lip, d, that projects over the needle, combined with a looper and needle and with fabric-feeding mechanism, substantially as described.

3. In. a sewing-machine, the Vertically and horizontally adjustable sectional looper h H, combined with complemental stitch-forming and feeding mechanism, substantially as described, and with the guard or protector I, having an oblique slot for a needle, substantially as specified.

4. The looper-bar 1i, having horizontal socket 6 extending from its end inwardly, combined with the rod h, having nearly-vertical socket 'i, the rod h passing within the horizontal socket e, and with the looper II, that is held in said socket 'L', and with a needle and feeding mechanism, substantially as described.

5. The combination, with the feed-disks B D, of the two guides L L over the disk B, at opposite sides thereof, for keeping the edge of the fabric above the disk B from falling over, and with stitch-forming mechanism, whose needle J enters between the ends of said guides, as specified.

(5. The combination of the feed-disks B and D with the needle-guard I and the guides L L over the disk B, at opposite sides of the disk, and with stitch-forming mechanism, substantially as herein shown and described.
